Nucleotide - Wikipedia
Nucleotides are organic molecules composed of a nitrogenous base, a pentose sugar and a phosphate. They serve as monomeric units of the nucleic acid polymers – deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all life-forms on Earth.

Nucleotide | Description, Types, Function, & Facts | Britannica
A nucleotide is any member of a class of organic compounds in which the molecular structure comprises a nitrogen-containing unit (base) linked to a sugar and a phosphate group.

Nucleotide Definition, Structure, and Function
What Is a Nucleotide? A nucleotide is an organic molecule that serves as the building block for nucleic acids like DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). These molecules consist of three primary components: a nitrogenous base, a sugar molecule, and one or more phosphate groups.

Nucleotide - National Human Genome Research Institute
A nucleotide is the basic building block of nucleic acids (RNA and DNA). A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.

NCBI Nucleotide Archives - NCBI Insights
If you’ve been searching in Gene, Nucleotide, Protein, Genome or Assembly databases, you’ve probably noticed the new search experience we introduced in September to interpret several common language searches and offer improved results. We’re excited to announce we’ve added as-you-type suggestions to the search bar in these databases. Here’s a peek at the new menu in the NCBI Gene ...

Nucleotide: Structure, Types, and Biological Functions
A nucleotide is a pentose sugar linked to a nitrogenous base and a phosphate molecule. Nucleotides are the building blocks of DNA. Figure: Nucleotide. The nitrogenous bases are derived from two-parent compounds – purines and pyrimidines.

3 Parts of a Nucleotide and How They Are Connected - ThoughtCo
A nucleotide has three parts: a nitrogenous base, a pentose sugar, and a phosphate group. The nitrogenous base is attached to the first carbon of the sugar in nucleotides. The phosphate group bonds to the 5-carbon of the sugar and links nucleotides together.

10.2: Nucleotides - Chemistry LibreTexts
The repeating, or monomer, units that are linked together to form nucleic acids are known as nucleotides. The deoxyribonucleic acid (DNA) of a typical mammalian cell contains about 3 × 10 9 nucleotides.
